WILTON, Maine (AP) — One of the main attractions at this year's Wilton Blueberry Festival isn't a fruit — it's a set of giant inflatable human organs for people to walk through.

The Morning Sentinel (http://bit.ly/1rTfAgN ) reports the two-day festival will include an inflatable heart, lungs, and a 50-foot-long human body visitors can walk through to observe the way organs work. The festival's chairwoman says the festival is adding the giant organs to bring an educational aspect to the event.

The festival, which attracts more than 4,000 people to the western Maine town of 4,100 people, takes place Friday and Saturday.
